Australia records first bird flu case in a mammal

Australia has confirmed its first case of bird flu in a mammal after a long-nosed fur seal was found infected in South Australia. Federal Agriculture Minister Julie Collins announced the discovery, stating, "This is sadly our first confirmed case of H5 bird flu in a mammal in Australia." The seal was found at Beachport, approximately 300 kilometers south of Adelaide.

Collins acknowledged the development is concerning but noted it was not entirely unexpected, given the high rates of H5 bird flu infections observed in wild birds. "Although this is a concerning development, it is not unexpected for us to start to see infection in other wildlife, particularly in marine mammals, particularly in areas where there are high infection rates in wild birds," she told reporters in Hobart. She added that current advice indicates the detection is not associated with other sick or dead marine mammals.

The infection in the individual seal is believed to have occurred through exposure to infected wild birds or their shared environment. Since the outbreak began, Australia has recorded 298 positive H5 bird flu events. Minister Collins reassured the public that there is currently no evidence of the virus affecting poultry or agricultural livestock. She plans to travel to South Australia in the coming days to discuss the state's response to the bird flu situation.
